Methytetrahydrofuran - MTHF

This fuel can be created from biomass using a process
called Biofine12. It has interesting prospects because
the intermediate between lignocellulose and MTHF
(called levulinic acid) can be reacted with ethanol to
make a good quality biofuel called ethyl levulinate.
Levulinic acid can be used as a ‘platform chemical’ 
to make things like nylon and synthetic rubber in
addition to a host of agrichemicals and other products.

Chicken feathers

Chicken feathers have 12% fat that can be removed with hot water or steam, and processed into biodiesel. There is a lot of waste feather from the poultry industry, enough  to make 153 million US gallons of biodiesel annually in the U.S., and 593 million US gallons worldwide.

Microbes produce fuel and plastic from CO

The LanzaTech Process can convert carbon monoxide containing gases produced by industries such as steel manufacturing, oil refining and chemical production, as well as gases generated by gasification of forestry and agricultural residues,  municipal waste, and coal into valuable fuel and chemical products. 

The carbon monoxide containing gas enters the process at the bottom of the bioreactor, and is dispersed into the liquid medium where it is consumed by LanzaTech's proprietary microbes.

The microbes produce products that can be used directly as fuel or chemical products. These are  MEK, isopropanol, and 2,3-Butanediol. That’s a foundational chemical for making any number of products that are normally made with petroleum, including plastics and synthetic rubber as well as fuel.
